The first known case of the Sky-Raider occur in the summer of 1948 when an astonished crowd of New Yorkers looked into the sky to see an dog sled racing through the air driven by a man in a parka and his accomplices.  Stopping at the skyscraper offices of the National Securities Company, the henchmen quickly began to work to remove the save when Dr. Mid-Nite, who had witnessed their arrival as Charles McNider on the street below, burst into the room.    Immediately engaged by the lackey, Mid-Nite is caught off guard when the safe is thrown at him only to find it light as a feather.  The Sky-Raider then took advantage of the distracted hero to bind  him in liquid cement.  The criminals then loaded the captive Mid-Nite and the safe onto their floating sled and took off into the sky.

The criminals had made a hideaway in the secluded parts of the Adirondacks and enroute, the Sky-Raider drops the bound Mid-Nite into the depths of a nearby lake.  Fortuitously giant crayfish inhabited the lake and instantly attack, snapping away the adhesive bonds.  Arriving sometime later in their lair, the Sky-Raider and his minions were shocked to find Dr. Mid-Nite waiting for them, having identified their address from a call to local helium distributors.  After thrashing the criminals, Mid-Nite himself flew the gang and the safe back to New York on the sky-sled.  There he revealed the Raider’s secret, an extensive use of helium containing materials to lighten the weight and allow the appearance of flight.

The ultimate fate of the Sky-Raider is unknown.
